KynShot AR-15 Carbine Buffer - Light Gas
The KynSHOT RB5000L is a hydraulic recoil buffer specifically engineered for soft cycling or under-gassed AR-15 platforms. The RB5000L is optimized for use with Mil-Spec carbine buffer tubes (7” internal depth), and works with any standard buffer spring. The RB5000L can be easily installed as a direct drop-in replacement for existing buffer systems.
The RB5000L is ideal for AR-15's that fail to lock back on the last round when using a standard or heavier buffer system. Its lighter design requires less force to cycle, making it especially well-suited for low-velocity ammunition such as .300 Blackout. For setups running exclusively supersonic .300 Blackout, the RB5000 would be the appropriate buffer to use if the bolt cycles reliably and ejection is consistent.
Using patented technology, the RB5000L absorbs recoil energy from the bolt carrier’s rearward movement, helping to prevent bolt bounce during chambering. It reduces felt recoil by 30% or more, enhancing overall shooting accuracy while minimizing muzzle rise. Our testing also indicates faster target reacquisition, allowing shooters to maintain their sight picture and stay on target between shots.
